Endodontics at the coal face

Reality at the COAL FACE

Online and blended learning modalities have made education accessible to those whose lifestyle, work obligations or geographical location would otherwise deny them such opportunities. The enthusiasm with which such approaches to learning have been embraced has often overlooked those factors within physical and virtual learning spaces that impact on the educational experience.

Face Detection at the Low Light Environments

Today, with the advancement of technology, the use of tools for extracting information from video are much wider in terms of both visual power and the processing power. High-speed car, perfect detection accuracy, business diversity in the fields of medical, home appliances, smart cars, humanoid robots, military systems and the commercialization makes these systems cost effective. Among the most...

High-Power Lasers in Endodontics - Fiber Placement for Laser-Enhanced Endodontics: in the Canal or at the Orifice?

The aim of this review is to give a survey of the use of high-power lasers for root canal cleaning and disinfection. There are two approaches: the first using a fiber in a dry root canal and exposing the root canal wall to the laser light with a spiral motion, and the other using the fiber in irrigant in the root canal or at the orifice. The laser-target interaction is different: a direct expos...
